Feature Summary

• Constructed from Type 316 stainless steel for enhanced corrosion resistance in harsh industrial settings.
• Certified for hazardous locations including ATEX and IECEx standards for gas and dust atmospheres.
• Equipped with a lift-off door design and quarter-turn latches for secure access and maintenance.
• Includes three integrated gland plates to facilitate cable entry and wiring management.

Applications

• Protection of electrical equipment in Zone 1 or Zone 21 hazardous areas.
• Installation in chemical processing plants requiring high corrosion resistance.
• Mounting control devices in offshore oil and gas platforms.
• Enclosure for instrumentation in pharmaceutical manufacturing facilities.

Procurement Notes

Verify that the specific installation environment matches the enclosure's certification group (3Gp) and category. Confirm that the required cable entries align with the included three gland plates or plan for additional modifications if necessary. Ensure compliance with local regulations regarding UL 508A and CSA C22.2 standards for the intended application site.

Selection Notes

Select this model when high corrosion resistance is critical due to the Type 316 stainless steel construction. Choose this unit over aluminum alternatives for environments exposed to harsh chemicals or saltwater. Consider the external dimensions (18.03 x 15.04 x 6.3 inches) to ensure adequate space for internal components and wiring within the designated mounting area.

Part Context

This component belongs to the nVent Hoffman ZONEX series, which specializes in enclosures for hazardous locations. The ZONEX line is designed to meet rigorous international safety standards, providing robust protection for sensitive electronic and electrical equipment in explosive atmospheres where standard enclosures would pose a risk.

Replacement Considerations

Direct substitutes include other ZONEX models with similar dimensions and certifications, such as those with different gland configurations. Verify that any replacement maintains the same 316 stainless steel material grade and hazardous location ratings (ATEX/IECEx) to ensure continued compliance and safety.
